2025-04-23hwmon: (xgene-hwmon) Simplify PCC shared memory region handlingSudeep Holla1-35/+4
The PCC driver now handles mapping and unmapping of shared memory areas as part of pcc_mbox_{request,free}_channel(). Without these before, this xgene hwmon driver did handling of those mappings like several other PCC mailbox client drivers. There were redundant operations, leading to unnecessary code. Maintaining the consistency across these driver was harder due to scattered handling of shmem. Just use the mapped shmem and remove all redundant operations from this driver.

2025-04-23hwmon: (max34451) Work around lost pageWilliam A. Kennington III1-0/+16
When requesting new pages from the max34451 we sometimes see that the firmware responds with stale or bad data to reads that happen immediately after a page change. This is due to a lack of clock stretching after page changing on the device side when it needs more time to complete the operation. To remedy this, the manufacturer recommends we wait 50us until the firmware should be ready with the new page. Signed-off-by: William A.

2025-04-23hwmon: (max6639) Allow setting target RPMNaresh Solanki1-2/+14
Currently, during startup, the fan is set to its maximum RPM by default, which may not be suitable for all use cases. This patch introduces support for specifying a target RPM via the Device Tree property "target-rpm". Changes: - Added `target_rpm` field to `max6639_data` structure to store the target RPM for each fan channel. - Modified `max6639_probe_child_from_dt()` to read the `"target-rpm"` property from the Device Tree and set `target_rpm` accordingly. - Updated `max6639_init_client()` to use `target_rpm` to compute the initial PWM duty cycle instead of defaulting to full speed (120/120). Behavior: - If `"target-rpm"` is specified, the fan speed is set accordingly. - If `"target-rpm"` is not specified, the previous behavior (full speed at startup) is retained. This allows better control over fan speed during system initialization.

2025-04-23hwmon: (pmbus) Do not set regulators_node for single-channel chipsGuenter Roeck5-8/+20
Single-channel regulators do not need and should not have a "regulators" node. We can not entirely remove it due to existing bindings. To solve the problem for new drivers, provide additional macros PMBUS_REGULATOR_ONE_NODE and PMBUS_REGULATOR_STEP_ONE_NODE and convert existing drivers to use those macros. The exception is the ir38064 driver because its devicetree files and its description do not require or use the nested regulators node. Modify PMBUS_REGULATOR_STEP_ONE and PMBUS_REGULATOR_ONE to set the regulators_node pointer to NULL.

2025-04-23hwmon: (pmbus) Introduce page_change_delayWilliam A. Kennington III2-34/+36
We have some buggy pmbus devices that require a delay after performing a page change operation before trying to issue more commands to the device. This allows for a configurable delay after page changes, but not affecting other read or write operations. This makes a slight behavioral tweak to the existing delay logic, where it considers the longest of delays between operations, instead of always chosing the write delay over the access delay.

2025-04-20gcc-15: work around sequence-point warningLinus Torvalds1-3/+6
The C sequence points are complicated things, and gcc-15 has apparently added a warning for the case where an object is both used and modified multiple times within the same sequence point. That's a great warning. Or rather, it would be a great warning, except gcc-15 seems to not really be very exact about it, and doesn't notice that the modification are to two entirely different members of the same object: the array counter and the array entries. So that seems kind of silly. That said, the code that gcc complains about is unnecessarily complicated, so moving the array counter update into a separate statement seems like the most straightforward fix for these warnings: drivers/net/wireless/intel/iwlwifi/mld/d3.c: In function ‘iwl_mld_set_netdetect_info’: drivers/net/wireless/intel/iwlwifi/mld/d3.c:1102:66: error: operation on ‘netdetect_info->n_matches’ may be undefined [-Werror=sequence-point] 1102 | netdetect_info->matches[netdetect_info->n_matches++] = match; | ~~~~~~~~~~~~~~~~~~~~~~~~~^~ drivers/net/wireless/intel/iwlwifi/mld/d3.c:1120:58: error: operation on ‘match->n_channels’ may be undefined [-Werror=sequence-point] 1120 | match->channels[match->n_channels++] = | ~~~~~~~~~~~~~~~~~^~ side note: the code at that second warning is actively buggy, and only works on little-endian machines that don't do strict alignment checks. The code casts an array of integers into an array of unsigned long in order to use our bitmap iterators. That happens to work fine on any sane architecture, but it's still wrong. This does *not* fix that more serious problem. This only splits the two assignments into two statements and fixes the compiler warning. I need to get rid of the new warnings in order to be able to actually do any build testing. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2025-04-20gcc-15: add '__nonstring' markers to byte arraysLinus Torvalds4-5/+5
All of these cases are perfectly valid and good traditional C, but hit by the "you're not NUL-terminating your byte array" warning. And none of the cases want any terminating NUL character. Mark them __nonstring to shut up gcc-15 (and in the case of the ak8974 magnetometer driver, I just removed the explicit array size and let gcc expand the 3-byte and 6-byte arrays by one extra byte, because it was the simpler change). Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2025-04-20gcc-15: get rid of misc extra NUL character paddingLinus Torvalds2-2/+2
This removes two cases of explicit NUL padding that now causes warnings because of '-Wunterminated-string-initialization' being part of -Wextra in gcc-15. Gcc is being silly in this case when it says that it truncates a NUL terminator, because in these cases there were _multiple_ NUL characters. But we can get rid of the warning by just simplifying the two initializers that trigger the warning for me, so this does exactly that. I'm not sure why the power supply code did that odd .attr_name = #_name "\0", pattern: it was introduced in commit 2cabeaf15129 ("power: supply: core: Cleanup power supply sysfs attribute list"), but that 'attr_name[]' field is an explicitly sized character array in a statically initialized variable, and a string initializer always has a terminating NUL _and_ statically initialized character arrays are zero-padded anyway, so it really seems to be rather extraneous belt-and-suspenders. The zero_uuid[16] initialization in drivers/md/bcache/super.c makes perfect sense, but it isn't necessary for the same reasons, and not worth the new gcc warning noise.

2025-04-20gcc-15: acpi: sprinkle random '__nonstring' crumbles aroundLinus Torvalds4-5/+5
This is not great: I'd much rather introduce a typedef that is a "ACPI name byte buffer", and use that to mark these special 4-byte ACPI names that do not use NUL termination. But as noted in the previous commit ("gcc-15: make 'unterminated string initialization' just a warning") gcc doesn't actually seem to support that notion, so instead you have to just mark every single array declaration individually. So this is not pretty, but this gets rid of the bulk of the annoying warnings during an allmodconfig build for me. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2025-04-20gcc-15: make 'unterminated string initialization' just a warningLinus Torvalds1-0/+3
gcc-15 enabling -Wunterminated-string-initialization in -Wextra by default was done with the best intentions, but the warning is still quite broken. What annoys me about the warning is that this is a very traditional AND CORRECT way to initialize fixed byte arrays in C: unsigned char hex[16] = "0123456789abcdef"; and we use this all over the kernel. And the warning is fine, but gcc developers apparently never made a reasonable way to disable it. As is (sadly) tradition with these things. Yes, there's "__attribute__((nonstring))", and we have a macro to make that absolutely disgusting syntax more palatable (ie the kernel syntax for that monstrosity is just "__nonstring"). But that attribute is misdesigned. What you'd typically want to do is tell the compiler that you are using a type that isn't a string but a byte array, but that doesn't work at all: warning: ‘nonstring’ attribute does not apply to types [-Wattributes] and because of this fundamental mis-design, you then have to mark each instance of that pattern. This is particularly noticeable in our ACPI code, because ACPI has this notion of a 4-byte "type name" that gets used all over, and is exactly this kind of byte array. This is a sad oversight, because the warning is useful, but really would be so much better if gcc had also given a sane way to indicate that we really just want a byte array type at a type level, not the broken "each and every array definition" level. So now instead of creating a nice "ACPI name" type using something like typedef char acpi_name_t[4] __nonstring; we have to do things like char name[ACPI_NAMESEG_SIZE] __nonstring; in every place that uses this concept and then happens to have the typical initializers. This is annoying me mainly because I think the warning _is_ a good warning, which is why I'm not just turning it off in disgust. But it is hampered by this bad implementation detail. [ And obviously I'm doing this now because system upgrades for me are something that happen in the middle of the release cycle: don't do it before or during travel, or just before or during the busy merge window period. ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This caused a memory leak. Free the hashes that are pointed to by the pointers when they are replaced. - Fix size initialization of ftrace direct function hash The ftrace direct function hash used by BPF initialized the hash size incorrectly. It checked the size of items to a hard coded 32, which made the hash bit size of 5. The hash size is supposed to be limited by the bit size of the hash, as the bitmask is allowed to be greater than 5. Rework the size check to first pass the number of elements to fls() and then compare that to FTRACE_HASH_MAX_BITS before allocating the hash. - Fix format output of ftrace_graph_ent_entry event The field depth of the ftrace_graph_ent_entry event is of size 4 but the output showed it as unsigned long and use "%lu". Change it to unsigned int and use "%u" in the print format that is displayed to user space. - Fix the trace event filter on strings Events can be filtered on numbers or string values. The return value checked from strncpy_from_kernel_nofault() and strncpy_from_user_nofault() was used to determine if reading the strings would fault or not. It would return fault if the value was non zero, which is basically meant that it was always considering the read as a fault. - Add selftest to test trace event string filtering In order to catch the breakage of the string filtering, add a self test to make sure that it continues to work. * tag 'trace-v6.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: selftests: Add testing a user string to filters tracing: Fix filter string testing ftrace: Fix type of ftrace_graph_ent_entry.depth ftrace: fix incorrect hash size in register_ftrace_direct() ftrace: Free ftrace hashes after they are replaced in the subops code ftrace: Reinitialize hash to EMPTY_HASH after freeing ftrace: Initialize variables for ftrace_startup/shutdown_subops()
